Abstract: 1,199,354. Automatic train control; electrically continuous track. WESTINGHOUSE ELECTRIC CORP. 7 Oct., 1968 [29 Nov., 1967], No. 47393/68. Heading B7H. In an automatic train control arrangement in which continuous track 10 is divided into a series of track circuits by shorting bars 16 and in which speed information is transmitted to a train by a binary coded signal modulated on the track circuit signal, the number of different track circuit signal frequencies required to operate the arrangement safely is reduced by making the track circuit receivers also selective to the phase of the binary coded modulating signal. As shown in Fig. 2, track circuit signals of three frequencies f 1 , f 2 , and f 3  are used and applied in repeated sequence to succeeding track circuits, in addition each track circuit signal is modulated by a binary speed signal, e.g. 101011 representing a required speed of 50 m.p.h., the phase of which is varied to provide the six-phase different modulating signals shown. The signal applied to modulate a track circuit signal is also applied to the associated track circuit receiver for comparison purposes. The train carried receiver 28 is responsive to any of the frequencies f 1 -f 3  and provides a control signal indicative of required speed.

Filed: 1963-12-02
Abstract: 1,064,573. Extruding thermoplastic tubing. PLASTIVAL S.A. Dec. 2, 1963 [Dec. 7, 1962], No. 47430/63. Heading B5A. Thermoplastic hollow bodies are produced by extrusion through a nozzle of standard outline and then formed to the desired profile by passage through at least one outline shaping device to give the desired profile, the body being urged against the inner wall of the device whilst still plastically deformable, under the action of a compressed fluid, the hollow body being finally hardened by cooling. Tubing extruded through die 2 is fed through rollers R into the outline shaping device C to be urged against the inner wall of the latter, both by the pressure of fluid applied through the interior of the tubing and by external suction applied by a suction pump 9. It is cooled in chamber C by ducts 5, 6 and finally quenched in a bath B, before passing between drawing off means T. A rubber diaphragm between flanges M, attached at 8 to cable 7, is used to maintain pressure inside the tubing during the extrusion process. In modifications of the process jaws in place of rollers R, or more than one outline shaping devices in series may be used for producing more complicated profiles, whilst bodies with sharp outlines may be formed by inserting wedges (c) in a suitably shaped nozzle (Fig. 5, not shown).

Patent GB-1537816-A (GB)
Title: Bonding crystals
IPC: H01L41/313
Filed: 1977-11-16
Abstract: A method of bonding two crystals together is disclosed. A bond enhancing material such as chromium (Cr) is vapor deposited on one crystal, and on this is vapor deposited a noble metal such as gold (Au). On the other crystal a low melting point metal such as tin (Sn) or indium (In) is vapor deposited. In the case of In this can either be directly on the crystal or on a layer of bond enhancing material; in the case of Sn this must be on a bond enhancing material. On top of the low melting point metal a layer of the same noble metal is deposited to prevent oxidation thereof. The noble metal layers are brought into contact with each other in vacuum or inert atmosphere and pressure applied thereto at a temperature of 100 DEG  C to 150 DEG  C in the case of In and 100 DEG  C to 200 DEG  C in the case of Sn. The low melting point metal will diffuse into the noble metals and across the interface causing a bond to form by elimination of the boundary between the crystals.

Title: Counters
IPC: G06F7/62
Filed: 1973-10-12
Abstract: 1450569 Price x quantity calculators; pulse frequency multiplication HOECHST AG 12 Oct 1973 [16 Oct 1972] 47740/73 Heading G4D The Specification describes an arrangement for calculating the total price of items produced by a machine such as a photocopier where the itmes are priced on a scale reducing with larger quantities. Machine cycles are sensed and for each machine cycle a number of pulses is released to a counter, the number being dependant on the rating of the individual cycles which rating depends on the position of the cycle in a sequence of cycles. In Fig. 1 a photocopier 1 produces copies until a number set at 2 is reached by a counter 4; the counter 4 issues a standardized pulse 50 each time the machine produces a copy. These pulses are applied to a counter 12 arranged to cyclically mark its outputs 121-1250. On production of the first copy output 121 is marked, setting a bi-stable 131 to apply to the input of a variable frequency oscillator 17 a voltage set by a resistor 141. The oscillator 17 is triggered only during the period of pulse 50 and in that time delivers a number of pulses dependant on the setting of resistor 141 to the counter 10. The same number of pulses is released by the second copy. For the third copy output 123 of counter 12 is marked to set a bi-stable 132 and reset 131; a smaller number of pulses is then released dependant on the setting of a resistor 142. Similarly for the fifth and subsequent copies the number of pulses released depends on reistor 143. A further price reduction may be made after the fiftieth copy by using a further bi-stable and variable resistor at the output 1250 of counter 12; thereafter counter 12 stops counting and all copies are priced the same. The number of copies at each price can be adjusted by varying the connections. The frequency characteristic of oscillator 17 is such that the counter 10 registers in suitable units the price of the copies directly; to allow for changes in basic price, e.g. for different sized sheets, the characteristic may be variable, or a resistor 140 may be variable to change the applied control voltages or the period of the standard pulse 50 may be varied. At the beginning of copying the counters 4, 12 and bistables 131-133 are reset by diodes 20-204 and contact 19. In a modification (Fig. 2, not shown) the bistables 131-133 are omitted each output of counter 12 directly feeding a resistor 141-143 by way of a diode (31-350). In a further modification (Fig. 3, not shown) a fixed frequency oscillator 17 is used and triggered for different periods dependant on which of a set of monostables (181-183) is triggered by the outputs 121-1250. In an alternative modification the settings of bi-stables 131-133 starts the oscillator and it is stopped when a further counter (300) reaches the number of pulses demanded by the particular bi-stable (Fig. 4, not shown). In each case lamps 161- 163 are arranged to indicate which price is being charged.

A method of forming concrete or ceramic blanks such as steps, comprises pouring an excess of concrete or ceramic into a mould 6, lowering a ram 1 such that the base 9 thereof closes the mould and compressing the concrete and squeezes out the excess. When the material has set, the ram is moved horizontally from the mould on a roller-mounted carriage 3 running in upper guides 2 before being raised to the position shown in dotted lines prior to being moved once more into the moulding position. While the ram is withdrawn the mould 6 is tilted and the blank removed. The mould may be vibrated during pressing and may also contain various inserts (13), (17), (19), (21) which are adjustable to give a varying profile to the blanks, Figs. 3-9 (not shown). In a modification (Figs. 16-19) the material is poured into a mould comprising a base palette 205, spaced from a mould table (203), and a profiled front wall 214 pivotable downwardly about a pivot 215. A press-die 209 is pivoted vertically downwardly via a two-armed lever 218 and piston 219 to compress the material, a front press (211) compressing the excess concrete 204a when a lever 226 is manuallyoperated, a flange 211a on the press (211) being guided downwardly over the upper part 209b of the die 209. Side walls (207), (208) and end wall 206 of the mould are withdrawn by foot-operated linkages, the wall 206 also being vertically reciprocable to scrape the end of the moulded blank. The mould may be vibrated, the blank and palette being removed by a fork-lift truck when the press-die is pivoted to the position shown in dotted lines and the walls 204, 206 (207), (209) are pivoted downwardly. In a further modification, Figs. 20, 21 (not shown), side walls (302), (303) are adjustable horizontally to vary the width of the mould while the moulding machine itself, including a belt driven vibrator is enclosed in sheet-metal cladding (316), (317), (318).

Abstract: 1315022 Catalytic recombiner for secondary battery OLDHAM INTERNATIONAL Ltd 12 Oct 1970 [15 Oct 1969] 48417/70 Heading B1F [Also in Division H1] . Catalytic recombination of hydrogen and oxygen released from a secondary battery during charging is effected by using a catalyst structure C, Fig. 3 comprising an inner catalyst N, Fig. 8 which has a high level of activity, surrounded by catalyst M which has a low level of activity which increases as it is heated and while - capable of recombining hydrogen and oxygen gas at a raised temperature at or below 250C. Thus initially the gas mixture passes through catalyst M and reacts exothermically on catalyst N. The heat thus generated accumulates and heats catalyst 17 so that reaction takes place on catalyst M. The effect is stated to be that as the gas pressure in the battery increases, the rate of rise of temperature of the catalyst decreases, and the temperature may even decrease. The catalytic material may be such that when exposed to a gas pressure of up to 4 atmospheres of H 2  and O 2  in stoichiometric ratios, its temperature will not rise above 600C. Catalyst N may comprise cylindrically shaped alumina pellets with an internal surface area of about 90 sq m/g impregnated or coated with 0.5% Pd by weight. Catalyst M may be cylindrically shaped pellets of alumina having an internal surface of less than 1mg m/g impregnated or coated web 0.01% Pd by weight.
